Proposal 5 Goby ROS Gateway

Many robotics applications are using ROS. We will want to be able to directly connect Goby3 with these various ROS systems.

Possible implementation paths:

• Use similar design to goby_moos_gateway, with user-customizable shared library plugins.
• Handle ROSMsg directly as a Goby3 marshalling scheme. This is not mutually exclusive with the previous option.
